Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To investigate the awareness of radon exposure hazards among non-uranium miners in Chongqing, China. Methods A survey was conducted among 177 male miners from eight non-uranium metal mines in Chongqing to collect data on basic information, personal habits, and the rate of radon awareness. Factors affecting radon awareness were analyzed using chi-square test and logistic regression model. Results The awareness rate of radon among miners was 23.73%. The chi-square test indicated significant difference in the radon awareness rate among miners with different levels of education (χ² = 10.28, P < 0.05), while there was no significant difference across different ages, years of work, labor relations, job categories, and types of miners (P > 0.05). Binary logistic regression analysis showed that a college (junior college) or higher level of education, a high school level of education, and working in mines were factors affecting the radon awareness among miners (χ² = 4.030, 9.150, 11.776, P < 0.05). Conclusion Miners lack awareness of radon, and there is an urgent need to strengthen education and propaganda regarding the hazards of radon.

Objective:To investigate the radon exposure levels and health effects among non-uranium miners in Chongqing.Methods:From June 2022 to December 2023, a survey was carried out on basic information, radon exposure and occupational health status of 110 male miners with good cooperation attitudes in 6 non-uranium metal mines in normal operation in Chongqing. The logistic regression model was utilized to statistically analyze the impact of miners′ individual radon doses on abnormalities in chromosomal aberration analysis, micronucleus examination, tumor marker tests, and pulmonary CT imaging.Results:Monitoring results from passive integrated radon personal dosimeters indicated that three miners had an annual dose exceeding 2 mSv. Logistic regression analysis revealed that abnormalities in pulmonary CT imaging were associated with miners′ age, tenure, and alcohol consumption ( χ2=12.18, 9.63, 4.87, P<0.05), with no significant correlation with smoking or individual radon dose. There was a significant correlation between individual radon dose and abnormalities in tumor markers; for every additional 1 mSv of effective dose from radon and its progeny, the risk of abnormality increased by 2.25 times ( χ2=4.57, P < 0.05). Conclusions:Some miners in Chongqing are exposed to an annual dose exceeding 2 mSv, and there is a correlation between individual radon doses and abnormalities in lung cancer serum tumor markers. It is necessary to focus on monitoring the radon exposure risks for miners, carry out regular health checks, and enhance the health protection for the miner population.

BACKGROUND:In recent years,computer-assisted navigation has gradually attracted attention in the medical field.Some scholars have reported that the clinical effects of computer navigation in total knee arthroplasty vary.To explore the clinical effect of the new generation of Brainlab Knee 3 navigation system,this study is conducted. OBJECTIVE:To analyze the application effect of computer navigation system(Brainlab Knee 3)combined with gap balance technology in total knee arthroplasty. METHODS:A total of 71 patients received total knee arthroplasty at the Department of Joint Surgery of Dalian Second People's Hospital from November 2020 to May 2021.In the navigation group,35 patients underwent total knee arthroplasty by computer navigation combined with gap balance.In the traditional group,36 patients underwent osteotomy with traditional surgical instruments.The difference between medial and lateral joint spaces,knee range of motion,hospital for special surgery knee score,hip-knee-ankle angle,deviation values of coronal femoral component angle,coronal tibial component angle,and sagittal tibial component angle were compared between the two groups. RESULTS AND CONCLUSION:(1)In the navigation group,the differences of intraoperative medial and lateral joint gap at knee extension 0,1,and 2 mm were found in 19,14,and 2 cases,respectively.The gap difference was 0 mm in 18 cases,1 mm in 15 cases and 2 mm in 2 cases at 90° degree knee flexion.In the traditional group,the gap difference at knee extention was 0 mm in 10 cases,1 mm in 20 cases,and 2 mm in 6 cases.The gap difference at 90 degree knee flexion was 0 mm in 10 cases,1 mm in 15 cases and 2 mm in 8 cases.(2)The operation time in the navigation group was longer than that in the traditional group(P<0.05),and two patients in the navigation group developed lower limb intermuscular vein thrombosis after surgery,and none of the patients in the traditional group had complications.(3)The range of motion between the two groups increased significantly at 6 and 12 months after surgery,and the range of motion in the navigation group was higher than that in the traditional group(P<0.05).(4)At 12 months after surgery,the hospital for special surgery knee scores of both groups increased significantly,and the hospital for special surgery knee score in the navigation group was higher than that in the traditional group(P<0.05).(5)At 6 months after surgery,the deviation values of hip-knee-ankle angle,coronal femoral component angle,coronal tibial component angle,and sagittal tibial component angle of navigation group were significantly lower than those in the traditional group(P<0.05).(6)The results showed that computer navigation technique combined with gap balance in total knee arthroplasty had advantages in postoperative range of motion,lower limb alignment and the accuracy of tibial prosthesis component position,and joint function recovered well.

Objective To investigate the effects of chronic starvation stress on the proliferation and migration of colorectal cancer cells, as well as the underlying mechanisms. Methods By using prolonged serum starvation to simulate chronic starvation stress in tumor cells, we established enduring serum-deprived models of SW480 and DLD-1 cells and observed cellular morphological change. Effects of prolonged serum starvation on SW480 and DLD-1 proliferative and migratory capabilities were assessed using CCK-8 and Transwell assays. Differential gene-expression analysis on SW480 cultured with 1% FBS or 10% FBS medium was followed by GO and KEGG pathway assessments. Migration-related protein interactions were explored using String database and Metascape software, leading to 16 genes being selected for RT-qPCR validation. Protein levels of ITGB1 and key molecules in the relevant pathways were measured. Mobility changes in SW480 were observed through Transwell assay after ITGB1 knockdown or STAT3 inhibition. Results Prolonged serum starvation significantly inhibited the proliferation of SW480 and DLD-1 cells, and DLD-1 mobility, while enhanced SW480 migration. Transcriptome analysis revealed that prolonged serum deprivation caused the upregulation of 3016 genes, among which 283 were involved in cell migration. Metascape analysis identified the correlations among potential core genes ITGB1, CD44, TNS1, STAT3, etc. Prolonged serum deprivation increased the mRNA levels of VTN, TNS1, VEGFA, STAT3, and ITGB1 while also increasing the protein levels of ITGB1 and MMP2 and the phosphorylation levels of JAK2 and STAT3. Mobility reduction in prolonged serum-starved SW480 cells was achieved through ITGB1 knockdown or a STAT3 inhibitor. Conclusion Colorectal cancer cells can endure chronic starvation stress which enhances migration capability by upregulating ITGB1 expression.
